POS stands for Point of Sale. A Point of Sale System is a combination of hardware and software at the cash register as well as digital payment capabilities, allowing businesses to process payment from their customers either in person, over the phone or through the internet. But POS Systems can also do a lot more than just process payments. They print receipts, track sales, keep track of inventory, provide information about business performance etc... At this time, ZenDelivery has a native integration with the POS Clover. More to come soon. If the Restaurant wants a POS integration but is not using Clover, we need to use a 3rd Party Aggregator like Chowly.
